This inventionrelates to grates for oil and 7 gas stoves and to the typeof gratesshown and described in Letters Patent No. 1,408,235 grantedtome February 28, 1922 and more particularly to airimprovenient'inthe'construction ofgrates as shown and described in my copendingapplication,

Serial No. 7 4A,- 317 filed October: 18, 192d.

The grates made in accordance w'ith myv present invention areconstructed to include all the advantages of the form of grate as shownand described in my apphcation aforesaid, and in carrying outthe'invention the grate made in accordance therewith invclii'desaplurality of bars preferably made of band steel and each bent at one endportion thereof with the extremity of each bent end portion suitablyconnected .to a part of the adjacent bar as will be hereinafter moreparticularly described. I r V In the drawing Figure 1 is a plan of aform of grate made in accordance with this invention. I 7

Referring to the drawing and particularly to Figs. 1, 2 and 3, a gratefor oil and gas stoves made in accordance with this. invention may. beconstructed to include a plurality of band m'etalbars preferably made ofsteel and rectangular in cross section as illustrated at 10 and 11. The.end portion of each of these band met-a1 bars is bent so or bolted orotherwise connected thereto so as to provide a central opening 0tappreciable diameter but as smallas possible at the centre of the grate.r

The grate structure shown in Figl is similar to that illustrated inFigs."1,] 2andf 3,- with theexception thateight-instead of six bars areemployed so that the angles betweehthe bars are appr0xiina'tely4 5": an-

gles. The bars in this case arem'ad'e fof the same kind of'metalandareindicated at 14: and 15.: The end portion ofleach bar is bent to formachannel, the parts of which are desi nated at 16 and'17,'16' beingthebase of the channeland 17 the extreinity'of I the bar; The extremitiesof tlie bars in" this construction are welded to the adjacent portion ofthe next adjacent bar so as to "pro vide central opening'ofappreciableextent at the centre 01 the grate. Also as indicated in'this structure,the. length of alternate bal's is greater than that of theintermediatebars, the extremities of the longer bars being indicated-at 18 and19 sothatthe grate is adapted; to fit within a squareope'ning in the upperportion ofthe stove instead of in round opening as when thegarms of thegrate bars are all of equal length.

The form of theinvention shown in Fig.' 5 is also similar to that shownin Figs. 1'

and 4, except that in this instance the end portions of each bar arebent to a substan-i tially -V shape. In this figure the bars areindicated at 20 and 21 and the bent 'extre'mi ties thereof at'22 and 23,22 being an angle of theV and 23 the extremity of the bari The extremity23 of each bar is suitably connected to the adjacent portion of the nextsucceeding barby being welded or, otherwise connected thereto. In thisstruc' ture the opening atthe centre of the grate is relatively smallerthan that in the types of the invention hereinbefore described. 1

In the form of the invention shown in Fig. 6, the ad acent grate barsare indicated at 24 and 25. The extremity of eachgrate, I

bar is bent on itself at opposite angles, for example the end of thegrate bar'24c is so bent atoneend as to provide a portion 26 at oneangle thereto and a portion 27 at an opposite angle thereto. In thisstructure as clearly illustrated in this figure, the eXtremity 27 of thebar 24 is adapted to abut against and to be connected to the'portion 28of the next adjacent bar 25 by being welded or riveted or otherwise:co-nnecte thereto, each ofthe bars being similarly connected to the nextadjacent bar so as toform an opening of appreciable extent at i1,.=%A"g"rate bar for 011 an 'g s" M the like, comprising a; plurality;of meta] bars each having a :bent end portion with the 1 extremityjoofthe bent end portion 01 yfbachfbar connected to an adjacent; portionof the next adjacent ban; ,7
